Zimmerman's attorneys wanted to speak with Crump about information he gathered after Martin's death.

Crump claimed he should not be deposed because of attorney-client privilege. The judge agreed and denied the motion.

O'Mara filed another motion, asking the judge to reconsider, but she ultimately came to the same decision on Thursday morning.

Attorneys for Zimmerman seek another hearing

Zimmerman's lawyers released a statement online about a canceled hearing, saying the court did not discuss foregoing the hearing with the defense.

"The court did not consult with the defense before canceling the hearing," a statement on gzlegalcase.com reads. The website is run by the Mark O'Mara law firm, which represents Zimmerman.

The attorneys are seeking another hearing in the case to settle several matters.

"As there are only 74 days until trial, and as there are Motions before the Court, we hope to appear before the Judge for pending matters before the next hearing currently scheduled for April 30," they said in the statement.

George Zimmerman is accused of killing 17-year-old Trayvon Martin in a Sanford townhouse complex. Zimmerman claims the shooting was self-defense.
